How does polyester fiber acoustic panel compare with sound-absorbing cotton? Many people will think that these two are cotton-like objects, the same sound-absorbing products, there should not be much difference between the two.

1 polyester fiber sound-absorbing board is composed of 100% polyester fiber raw materials, is similar to cocoon cotton-like appearance, pinched in the hand also has cotton-like flexibility, but it can be directly used to paste the wall decorative sound-absorbing board products, fireproof, mildew-proof, moisture-proof, effective absorption of medium and high frequency sound, its decorative performance is good, color modeling choices, everything, so polyester fiber sound-absorbing board is more widely used. Polyester fiber sound-absorbing board belongs to the type of porous material sound absorption in the classification of acoustic materials, which is destined to be the reason for the good sound absorption effect in the middle and high frequencies, especially in the high-frequency sound absorption coefficient can reach about 0.8-1.0, and become an efficient sound-absorbing material in the broadband area in one fell swoop.　

2 polyester fiber sound-absorbing board not only has sound absorption performance but also has thermal insulation effect, easy transportation and installation, polyester fiber through foreign imported equipment pressed board density uniform, wear-resistant, certain toughness, not easy to damage, but also anti-collision, but also the ideal sound-absorbing material for interrogation rooms.

3 Polyester fiber sound-absorbing board has more than 30 kinds of plain board colors, including embossing and printing up to more than 100 kinds, and the construction is simple, with a utility knife to cut arbitrarily, is the only sound-absorbing material of any specification, making the design of the acoustic space more diverse.

Sound-absorbing cotton

The main raw material of sound-absorbing cotton is wool with a small amount of chemical added ingredients, fireproof, mildew-proof, heat insulation and sound absorption performance, many will also add a layer of aluminum foil, played a moisture-proof effect, but can not be directly used to paste the wall surface, most of them are used in sound-absorbing panels as auxiliary materials, can also be laid around the sewer pipe, with a good sound absorption effect.

Polyester sound insulation cotton material can be processed into board or felt material placed on the inside of the wall and the board composed of composite sound absorption sound insulation wall to achieve the expected sound absorption effect, in the indoor ceiling can be processed into sound absorption ceiling suspended under the indoor roof. In this way, the veneer polyester sound-absorbing cotton ceiling panel requires relatively light weight, simple structure and convenient workmanship.

How does polyester fiber acoustic panel compare with sound-absorbing cotton? Compared with the difference between the two is still very obvious, polyester fiber sound-absorbing board can be directly pasted on the wall surface to play a good decorative effect, and sound-absorbing cotton is mainly used as auxiliary materials in the sound-absorbing board, heat insulation, sound absorption effect is good
